Sphinx test: What it is, how it works and how to prepare

Found our content helpful?

Key takeaways

The sphinx test is Epic Systems’ proprietary aptitude assessment for technical hiring, covering logic, numbers, reading, and code-style reasoning.

The test evaluates four domains: logical reasoning, numerical reasoning, verbal reasoning, and computational tools. No healthcare knowledge is required.

The computational tools section is built on an invented programming language, so rule-following matters more than prior coding experience.

Candidates are never shown their score. Epic uses results internally to compare applicants without sharing thresholds.

Two to three weeks of structured practice across all four domains gives candidates the best foundation.

The sphinx test is Epic Systems’ own aptitude assessment, sent to candidates for implementation and technical roles after the first phone screen.

It runs roughly 60 to 90 minutes and covers four domains: logical reasoning, numerical reasoning, verbal reasoning, and computational tools. No healthcare knowledge is tested anywhere in it.

Epic never shows you the score, so there is no threshold to aim at. Candidates who clear it typically spend two to three weeks practicing across all four domains. Epic rejects more than 90% of applicants for these roles, according to accounts across r/healthIT and alumni forums. The sphinx test is the earliest hard filter in that funnel.

This guide covers what each section asks, how the format works, and a week-by-week preparation plan. It also sets out what happens after you submit.

What the sphinx test is and why Epic uses it

The sphinx test is a proprietary aptitude assessment administered by Epic Systems during recruitment for technical and implementation roles. It measures raw cognitive aptitude rather than knowledge. Epic is not checking whether candidates understand practice management software or clinical workflows on day one.

What the company wants is candidates who reason through problems methodically, work with numbers accurately, and read dense material closely. It also wants the structured thinking that software implementation demands.

Epic developed the assessment internally, which is why preparation resources are thin. No official study guide exists. The company does not publish the question format, section breakdown, or passing threshold. What is known comes almost entirely from candidate accounts shared in health IT communities over several years.

The reasoning behind the test makes sense once you understand the role. Implementation consultants at Epic spend years configuring EMR software inside hospital environments, translating clinical workflows into software logic.

That work requires comfort with abstraction, numerical accuracy, and the patience to read a specification carefully before acting on it. It also requires debugging a process when something does not behave as expected. The sphinx test screens for those capabilities before any domain-specific training begins.

Who has to take it

The test is required for candidates applying to Epic’s Technical Problem Solver track and related implementation consultant roles.

These positions sit at the intersection of EHR implementation and client-facing project delivery. Not every Epic role requires it. Customer service, sales, and administrative positions follow different screening paths.

The roles most commonly associated with the sphinx test include:

• Technical Problem Solver – Epic’s primary entry-level implementation track for candidates without a clinical background
• Implementation Consultant – the role responsible for configuring Epic modules within health system environments
• Software Developer – candidates for software roles may encounter related technical assessments

Candidates entering healthcare IT through a non-clinical route often find Epic’s implementation track appealing, because no prior healthcare experience is required at hire. The sphinx test is the mechanism Epic uses to filter for aptitude in place of a clinical or technical CV.

Format and structure of the assessment

The sphinx test is administered online, typically sent to candidates after an initial phone screen. The exact question count and time allocation are not officially published. Based on community accounts, the test runs between 60 and 90 minutes and covers four sections.

Candidates report that time pressure is moderate rather than severe. The harder logical reasoning problems can still consume time quickly if approached without a strategy.

Candidates misjudge the computational tools section more often than any other. It does not use Python, Java, or any language you can revise beforehand. Candidates report being handed a short reference sheet for a made-up language, then asked to trace what a few lines of it produce.

Prior programming experience helps only insofar as it makes if-then branches, loops, and variable assignment feel familiar. Careful rule-following beats fluency in any particular language.

Verbal reasoning is a separate section, and prep guides that describe only three domains leave it out. Epic implementation work involves reading specifications, build notes, and client documentation with precision, so the assessment checks that skill directly.

None of the test measures product knowledge, so reading up on practice management software features will not help you here.

What each question type looks like

Logical reasoning questions typically present a rule or pattern and ask candidates to identify what comes next or which item does not belong. Numerical questions involve reading a short dataset, often a small table or chart, and performing a calculation.

Verbal questions give you a paragraph of prose and a statement, then ask whether the passage supports it, contradicts it, or says nothing either way. Computational tools questions present a short block of invented code and ask what value a variable holds at the end.

Candidates consistently note that the questions rarely have obvious answers. Each is designed to separate a candidate who worked through the logic from one who guessed. Speed helps, but accuracy matters more.

How the test is scored

Epic does not share scores with candidates, and that is policy rather than oversight. After completing the sphinx test, candidates receive no numerical result, no percentile ranking, and no feedback on which sections went well.

The score exists internally at Epic and is used by recruiters to compare applicants. The hiring team may weigh it alongside phone interview performance, application background, and other signals when making a progression decision.

This opacity is frustrating but worth understanding clearly before you sit the test. Preparing obsessively for a passing threshold you cannot verify is counterproductive. The better framing is to prepare to perform at your honest ceiling, then let Epic’s internal process run its course.

Pass rate and difficulty

No official pass rate exists. Community estimates across r/healthIT and similar forums suggest the assessment is selective, and a meaningful share of candidates who reach this stage do not advance. Health IT hiring is competitive across the board, and HIMSS workforce research documents the staffing pressures behind it.

Difficulty is reported as moderate to high for candidates without recent practice on aptitude-style assessments. Candidates with a quantitative academic background in engineering, mathematics, computer science, or economics generally find the numerical and computational sections more manageable.

Those coming from liberal arts or clinical backgrounds often lose the most ground on computational tools, while picking up easy marks on verbal reasoning. The four-domain spread means no single background carries the whole test.

How to prepare for the sphinx test

Two to three weeks of structured daily practice is the preparation window most candidates report as sufficient. The proprietary format makes memorizing answers impossible, so the goal is fluency in the four cognitive skill areas instead. The plan below spreads those four domains across three weeks.

The following steps form a practical preparation sequence.

1. Start with a baseline diagnostic. Sit a free GMAT quantitative set, a free verbal reasoning set, and a free logical reasoning test without studying first. This shows you where your weakest domain sits before you invest time.
2. Target your weakest section first. Spend the first week on your lowest-scoring domain. If that is logical reasoning, work through 20 to 30 pattern-based puzzles daily. If it is numerical, drill percentage calculations, rate problems, and table reading until they feel automatic.
3. Drill verbal reasoning against the clock. Work through short-passage sets where you mark each statement true, false, or cannot say. This section rewards the discipline to answer only from the passage, without adding outside knowledge. Twenty minutes a day is enough.
4. Build computational familiarity in week two. Learn what a loop does, how a conditional branches, and how a function returns a value. Then practice applying a syntax you have never seen from a reference sheet, since that is the task Epic sets. Khan Academy’s computer programming introduction covers the concepts without requiring prior coding experience.
5. Practice under timed conditions. In the final week, simulate test conditions. No notes, no calculator unless permitted, a timer running. Time pressure changes how the brain processes familiar material, so meet it before test day.
6. Do not try to memorize question formats. The sphinx test is proprietary and no prep site holds its questions. Materials marketed as official Epic practice tests are reconstructions based on candidate reports. Use them to build general aptitude, not to expect identical questions.

The American Medical Informatics Association publishes careers and certifications guidance for people entering health informatics. AMIA does not address the sphinx test directly. Its competency frameworks for informatics professionals describe the same analytical skill set the test probes.

Sample practice questions, one per domain

These worked examples reflect the style of question candidates report encountering, one per domain. They are not Epic’s own questions. Use them to calibrate your thinking approach.

Logical reasoning sample: A, C, F, J, ? What comes next in the sequence? Each letter skips one more than the last. A to C skips 1, C to F skips 2, and F to J skips 3. The next step skips 4 letters, so J becomes O. Answer: O.

Numerical reasoning sample: A practice records 480 patient visits across 12 weeks. In the final 4 weeks, the weekly visit rate ran 15% above the first 8 weeks. How many visits fell in the final 4 weeks? Let x be the weekly rate for the first 8 weeks. Then 8x + 4(1.15x) = 480, so 12.6x = 480 and x = 38.1. The final 4 weeks run at 43.8 visits per week, giving roughly 175 visits.

Verbal reasoning sample: Passage: “The department moved to the new scheduling module in March. Since then, appointment no-shows have fallen. The module sends automated reminders, and staff also began calling high-risk patients in February.” Statement: “Automated reminders caused the drop in no-shows.” Answer: cannot say. The passage names two possible causes and a second one started earlier, so the text does not establish which produced the fall.

Computational tools sample: You are given a reference sheet for an unfamiliar language. The code reads: x = 5. Then: if x > 3 then x = x + 2. Then: if x > 6 then x = x * 2. Then: print x. What does it print? After line 1, x = 5. After line 2, x = 7, because 5 is greater than 3. After line 3, x = 14, because 7 is greater than 6. Output: 14.

What happens after you submit

After submitting the test, candidates typically hear back within one to three weeks. The timeline varies based on the volume of applicants Epic is processing and the urgency of the hiring need. Silence does not always indicate failure. Candidates who have heard nothing after three weeks can send a polite follow-up to their recruiter contact.

If the result is positive, the next step is usually a panel interview, often conducted virtually. This stage tests cultural fit and problem-solving approach rather than technical depth. Candidates who pass the sphinx test but are not progressed are rarely given a reason.

If the result is negative, candidates are typically not invited to reapply within a defined period, often 12 months based on community reports. That matters for anyone genuinely interested in Epic as an employer. Treat the sphinx test as a single high-stakes event rather than something to iterate on.

Implementation roles also exist at health systems, consulting firms, and smaller software vendors, many of which do not require a proprietary aptitude test at entry. A rejection from Epic closes one door rather than the career.

Common mistakes to avoid

Candidates who underperform on the sphinx test tend to share a predictable set of errors. Most are avoidable with awareness.

• Preparing for three domains instead of four. Many online guides describe logic, numbers, and code, then stop there. The verbal reading section catches unprepared candidates cold, so build it into your practice from day one.
• Over-preparing one section. Spending 90% of prep time on logical reasoning while neglecting the numerical section leaves an easy gain on the table. Distribute practice across all four domains, weighted toward your weakest area.
• Using generic IQ tests as primary preparation. Free IQ tests online measure something adjacent to the sphinx test, but not the same format. GMAT-style practice and basic programming logic exercises come far closer to the demands of the sitting.
• Assuming healthcare knowledge is tested. Candidates with clinical backgrounds sometimes over-study EHR features, expecting domain questions. The sphinx test does not assess this. Reasoning is what matters.
• Taking the test without simulating conditions. The home environment creates distractions. Find a quiet space, close all other browser tabs, and treat the sitting as you would an in-person exam.
• Giving up mid-sequence on hard logic problems. If a question does not resolve quickly, mark your best answer and move forward. Time spent agonizing over one question costs you accuracy on three others.

The discipline that carries a candidate through a 90-minute aptitude assessment also carries over into the job. Implementation consultants read a specification closely, check the numbers, trace the logic, and only then configure the build. That is the same loop the four sections measure.

Where this skill set lands once you are configuring Pabau

The work the sphinx test screens for is the work of configuring software around how a practice already runs. Most practices arrive at that project with scheduling in one tool, notes in another, and payments in a third.

Staff rekey the same patient details several times a day, and reporting means exporting spreadsheets and reconciling them by hand.

Practice management software like Pabau replaces that patchwork. Scheduling, clinical notes, online booking, payments, and reporting sit in one practice management app, on a single patient record. A change made at the front desk shows up wherever the practice needs it.

Implementation then becomes a configuration exercise rather than a data-plumbing exercise, which is the structured reasoning the sphinx test rewards. For a practice running Pabau, that means fewer duplicate records, shorter admin days, and reporting the owner can trust without rebuilding it each month.

Conclusion

Prepare for four domains, not three. That single decision separates the candidates who walk in ready. The rest meet the verbal reading section for the first time under a timer. The computational tools section deserves its own week, because it is the only part you cannot revise in advance.

Accept that you will never see the score. Preparing to a threshold you cannot verify wastes the two weeks you actually have. Prepare to your honest ceiling and sit the test once. Treat the outcome as Epic’s judgment rather than a verdict on your suitability for health IT.
